"The asteroid's arrival was preceded by a damaging meteor event in Russia on Friday - but indications from the meteor's path suggest that the two events are entirely unrelated - just a "cosmic coincidence", as Alan Fitzsimmons of Queens University Belfast told BBC News."

A once in a century meteor explosion occurs the same exact day as a very rare record breaking near miss asteroid pass.I'm not exactly sure that's a "coincidence".I'm sure their data suggests it may be unrelated, but the data they are using is limited trajectory data on the meteor, they don't have any data on such things as how the gravitational field of the asteroid might effect or send ripples in our magnetic field as it passes, and how that might effect small objects such as the meteor.

In my experience in nature, large objects are often grouped with one or two small one's as well.
